Heavy-Duty Shaker Screen Spherical Roller Bearings solve many problem. Available in SPAW, SPW, and SFCW types, these units utilize contact seals to combat heavy contamination issues. The spring-loaded contact seals offer better contamination protection and less grease consumption, while offering greater misalignment capability. Additionally, these units offer the same base-to-shaft-center height and bolt-hole positions as SAF units for easy replacement. Standard one-piece ductile iron housing offers better shock-loading characteristics and quicker mounting and dismounting, when compared to SAF units.
